3" might be doable with plenty of slope but I don't think I would risk it laying pretty flat for two reasons. Capacity and not much margin for error installing it.
We have our tile installed by a professional contractor. We're pretty flat & because of the slim margine of error he refuses to install 3". When we started having grid tile put in we went with 4" on 50'. At the time most were putting 4" on 60s at the time. I had a 70 ac field done half on 4 x50s & other have 4 x 40s. In a couple low spots we split the 50 in half but didn't split the 40s. That was over 10 years ago yield maps show an advantage of the 40s over the 50s but very little difference for the 25s over the 40. Since then we have been running the 4" on 40s.
A couple of neighbors were big into 3" on 30s but have since gone to 4" on 40 . |
